.Be it known that we, h'IAR'llN C. Konrn and Louis N. VLUKER'JY, citizens of the United States of America, and residents of Fort lVayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Vaporizers for ItIydrocarbon Engines, of which the following is a specification.

This invention relates to improvements in Vaporizers for hydrocarbon engines, of the class wherein the fuel mixture of gasoline and air supplied by a carbureter is subjccted to heat derived from the exhaustfrom the engine during its passage to the intake manifold of the engine. The object of the invention is to provide a single piece structure that may be interposed between the carbureter and intake manifold of an engine and connected up with the exhaust outlet ofthe engine, without the necessity of altering the engine or its appurtenances. Another object is to construct the device so as to cause the fuel mixture from the carbureter to spread and swirl during its passage through the heating chamber thereof.

The above objects are accomplished by the construction illustrated in the accompanying drawings in which Fig. 1 is a front end elevation of the device partly broken away; and

Fig. 2 is a vertical central section of Fig. 1 in a plane at right angles thereto, and including a portion each of a pipe leading from a carbureter and intake manifold connected therewith.

The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding characters.

The invention comprises a casting 1 having a chamber 2 with an inlet port 3 and outlet port 4 respectively at the front and back of the casting, which ports are located at the lower end of the casting. \Vithin the casting is a transverse partition 5 located midway between the inlet and outlet ports and extending upwardly into the chamber 2 partially dividing the same. In the upper portion of the partition 5 is formed a duct 6 that extends from one side of the casting to the other, the ends of the duct terminating in corresponding external bosses 7 which are connected in a pipe line 8 which is arranged to convey a portion of the exhaust from the engine by suitable connection: with the exhaust pipe (not shown) thereof.

Between the upper portion of the partition 5 and the front wall 9, through which the inlet port extends, are-arranged a series of divergent blades 10--11, that extend from the inlet port to the top of the partition, the upper end 12 of each blade being curved laterally away from the center line of the casting. V

The casting is positioned with its inlet port 3 in connection with the pipe 13 leading from a carbureter and its outlet port in connection with the intakemanifold 14: of the engine, bolts 15 extending through slots 16 in the casting and the flanges 13 and M of the carbureter pipe and manifold serving to hold the same together in proper alinement.

In the operation of the invention the partition 5 is heated by the exhaust passing through the chamber 6 therein, theblades 10 and 11 being also heated more or less by the conduction of heat from the partition. The fuel mixture supplied by the carbureter heated partition and between the hot blades into the chamber 2. During its passage between the blades the mixture becomes spread laterally because of the divergency of the blades, and is also caused to swirl in passing the curved upper ends thereof. In this manner the particles of liquid fuel become vaporized because of their contact with the heated walls of the partition and blades, and the vapor becomes more thoroughly mixed with the air in the chamber because of the swirling action induced by the curved ends of the blades. Thus,the fuel mixture reaches a homogeneous stage in the chamber before its admission through the outlet port into the intake manifold, with the result of more perfect combustion in the engine than in the ordinary practice.

What we claim is 1. In a vaporizer for an internal combustion engine, a single piece casting having a chamber therein with alined inlet and out-- let ports and a transverse partition dividing the lower part of the chamber between the ports, said partition having a duct in its upper portion above said ports the ends of said duct extend respectively through the correspondin sides of the casting, and a group of bla es divergently arranged, each of which is integral with and extends from the partition to the Wall of the casting in which the inlet port is located, the upper ends of the respective blades being curved away from the center line of the casting.

2. In a device of the class described, a casting having a chamber therein and alined inlet and outlet ports in its lower part for connection respectively with the carburetor and intake manifold of an engine, and having a partition in said chamber disposed at right angles to said ports, there being a duct extending through the partition from one side of the casting to the other in a plane above said ports, there being a series of divergently disposed blades, each extending from said partition to the Wall of the casting through which the inlet port extends.

In testimony whereof We afiix our sigma-- tures.
